Hello mother, hello father/Here's scenario planning fodder.
Things that happened in history on March 11 and could happen in some future scenario:
222: Elagabalus (a.k.a. Heliogabalus), Emperor of Rome, has a bad day and so does his mom. The Praetorian Guard assassinates them both, drags their mutilated bodies to the river Tiber, and dumps them in.
1641: Guarani forces in present-day Argentina, residents of a Jesuit "reduction" or reservation and led by Jesuit priests, defeat slave-raiding "bandeirante" forces loyal to the Portuguese crown in the Battle of Mborore. This is one of the early events that ultimately lead to the suppression of the Jesuits by the Pope in 1773.
1702: The Daily Courant, England's first national daily newspaper, is published for the first time, from their premises "against the Ditch at Fleet Bridge." It is a one-page broadsheet. Circulation is limited due to the lack of a Page Three.
1708: Queen Anne refuses Royal Assent to Parliament's Scottish Militia Bill; so far, this is the last time the sovereign has vetoed legislation in the United Kingdom.
1985: Mikhail Gorbachev is named the last General Secretary of the Communist Party of the Soviet Union. He pens a U.S. bestseller entitled Perestroika. This reporter developed a sense that the USSR might be doomed when he saw that one of the chapters was entitled "On to Full Cost Accounting!" (Exclamation point added for snideness.)
2011: Tohoku earthquake and tsunami destroys much of the Sendai region, Japan. It is the most powerful earthquake ever known to hit Japan, and one of the five largest earthquakes since modern records began to be kept in 1900. The quake and tsunami kill 15,881 people; 6,142 people were injured, and 2,668 people are still missing across 20 prefectures. The accompanying tsunami reached 133 feet in height in Iwate Prefecture and reached as far as 6 miles inland. Almost 700,000 buildings are damaged, with 129,225 collapsed and 254,204 "half collapsed." The earthquake is so powerful that the entire island of Honshu, main island of Japan, is moved eight feet to the east, and the earth is shifted on its axis by between four and ten inches. Three nuclear reactors suffer full meltdowns and Level Seven nuclear incidents, the first since Chernobyl in 1986. Japanese authorities ultimately say it will take decades to decontaminate the surrounding areas and to decommission the plants. But though six plant employees are killed by the tsunami and earthquake, no employees are directly killed by radiation, and the World Health Organization states in 2013 that local residents were exposed to so little radiation that it would not be detectable. Various scenarios of the future of the region are plausible.
